Strange desires

I have this strong desire to share my girlfriend with an older dominant man.
It started years ago while me and my ex were on vacation in Egypt. We were young, carefree and open to many adventures. while in Alexandria we met a shopkeeper who offered us a room in his house for free. Well nothing is for free as it turned out. Ditte my ex had a thing for older men. In the beginning she was not to happy about him touching her all the time, but later it became a turn on. He didn't take her by force, no he seduced her, and made me part of it.
I didn't see them fuck( I wish) but heard them. She told me later that it was some off the best sex she ever had, because he was so dominant. He was the first person to fuck her ass, and didn't even ask.
The three weeks we spend there changed my life profoundly.
During our years together Ditte and I often went to South Africa( I was born there) when there we often visited a certain jazz club, frequented by older black men. It was a dark, smoky place. Since I am not a big dancer Ditte usually went off with some of the local men to dance for a while. I still fantasies about what happened in those dark corners. She admitted to being kissed, felt up and even fingered, but never fucked.
The thought of all that old black men on her really turn me on.
I lost track with Ditte over the years, but would love to find a girl like her again.
The idea of her being used by older BBC or Arab just make me so hard, and if he was bisexual even better!
